PERF_STRING_COUNTER_HEADER structure (perflib.h)

Indicates where in the PERF_STRING_BUFFER_HEADER block that the string that contains the name or help string for the indicated performance counter starts. The PERF_STRING_COUNTER_HEADER structure is part of the PERF_STRING_BUFFER_HEADER block

Syntax

typedef struct _STRING_COUNTER_HEADER {
  DWORD dwCounterId;
  DWORD dwOffset;
} PERF_STRING_COUNTER_HEADER, *PPERF_STRING_COUNTER_HEADER;

Members

dwCounterId

The identifier of the performance counter.

dwOffset

The number of bytes from the start of the PERF_STRING_BUFFER_HEADER block to the null-terminated UTF-16LE data. A value of 0xFFFFFFFF indicates that the string is not present; in other words, that the value of the string is NULL.

Remarks

The PerfQueryCounterSetRegistrationInfo function called with the requestCode parameter set to PERF_REG_COUNTER_NAME_STRINGS or PERF_REG_COUNTER_HELP_STRINGS gets a PERF_STRING_BUFFER_HEADER block that contains one or more PERF_STRING_COUNTER_HEADER structures.
